MacBooks can easily last four to six years in a corporate environment - and heavy load on the battery drastically impact it in two years.

In my experience the battery was the issue for most MacBook users.

>True but how often is the battery the issue in an enterprise environment?

Biggest issue by far. We have a fleet of 100+ MacBooks in my office and expanded batteries are probably the only thing we have that goes wrong with them. They're rock solid otherwise. The new replaceable batteries is a huge deal.

Your parent commenter mentioned connector as well. What else couldn't be repaired on-site that could be repaired off-site? I'm pretty sure anything that for anything that couldn't be repaired on-site they're just going to replace the whole computer.
